Stop phoning me!

I made the mistake of taking a call and upgrading my policy recently, since then I have been phoned on my cell as well as my work number over and over again - sometimes twice within the space of 2 or 3 minutes. I have asked repeatedly that they make a note on their system not contact me on my cell phone as I deal with clients , but to instead leave a message at reception on my office and I will return their call. They phone before 08:00am and after19:00 pm.I then received a package with my new policy document and a \free gift"from Elizabeth Garcia and the phone calls escalated. I started receiving calls from both Platinum Life and Elizabeth Garcia. I phoned Platinum life yesterday and cancelled the policy upgrade and instructed them not to contact me - I would contact them if I needed anything. I work in financial services and so I am well aware that you cannot give out clients personal details for any marketing purposes without their consent"
